After-Hours Service Desk Voicemail Alerting

Let no important customer call go unnoticed

The Challenge

Even small and medium sized business are required to provide services at their customer’s fingertips. Offering a service or help desk with a 24/7 operated voice line is common.

It is however a challenge to staff those services during after-hours. Even for larger enterprises with low call volume it doesn’t make sense to staff such hotline around the clock. So, on-call or standby seems like a solution. It is however hard to pick up the phone in the middle of the night and to be fresh and bright in an instant when an upset customer calls.

While a voice mailbox sounds good it leaves you with the challenge of getting a reliable notification out when a customer left a voicemail. Such important call notification should never go unnoticed.


SIGNL4 is your solution and supports any voicemail service which can send you an email with the voicemail attached in WAV or MP3 format. Simply route such voicemail via email to your SIGNL4 team and SIGNL4 reliably notifies people on duty during after-hours. Open the SIGNL4 alert in the mobile app and press the ‘Play’ button to listen to your customer’s recording. Call him back instantly with a single touch.

  • notifies staff on duty upon a new voicemail via push, text and voice calls
  • notifies persistently until acknowledgement
  • escalates to a management person if an alert is not confirmed in time
  • digests emails with wav and mp3 attachments from your voicemail provider
  • plays wav and mp3 recordings within the mobile app
  • lets you call your customer with a single touch of the caller id is part of the email
